Go to the applications folder and find Logic Pro. Your high-quality recordings are at stake, so it’s worth backing up before you update. You get nearly 6,000 instruments and effect patches, together with 1,200 sampled instruments and a whopping 14,750 Apple Loops - music samples that can be played while inside the Live Loops Grid that Logic Pro shares with GarageBand for IOS. Although the basic install of the program requires only 6GB, installing the whole sound library needs 72GB. With so much power and so many choices you’re going to need to make space available. Logic Pro boasts nearly 2,000 definable key and MIDI commands, and - to help you experiment and get creative, there’s also a 200-step undo history, including plug-in and mixer editing undo.
